Logical OR Operator
When a compound expression contains subexpressions joined by the OR operator, the overall expression
is true if any of the subexpressions is true. Let’s use the following pseudocode as an example:

if (al > bl) OR (bl > cl)
X = 1

In the following implementation, the code branches to L1 if the first expression is true; otherwise,
it falls through to the second CMP instruction. The second expression reverses the > operator
and uses JBE instead:

cmp al,bl ; 1: compare AL to BL
ja L1 ; if true, skip second expression
cmp bl,cl ; 2: compare BL to CL
jbe next ; false: skip next statement
L1: mov X,1 ; true: set X = 1
next:

For a given compound expression, there are multiple ways the expression can be implemented
in assembly language.
